FELIX JULES BOSSET AND PHILIPPE CACHARD, OF LYON, FRANCE, ASSIGNORS TO SOGIETE ANONYME DES ANCIENS ETABLISSEMENTS BOSSET ET GACHARD, OF LYON,

FRANCE.

LOOIVL To all whom it may concern:

Be it lmown that we, FiiLrx JULns Bossnr and PHILIPPE CACHARD, citizens of the French Republic, residing at Lyon, in France, have invented a certain new and useful Improvement in Looms, of which the following is a specification.

The present invention relates to a loom for simultaneously weaving a plurality of webs with free selvages.

To this end a special disposition of the warp threads is adopted, so that at least two pieces of fabric are simultaneously woven side by side.

The improved loom in its most simple form comprises two shuttles moving simultaneously in the same direction, and three pickers, two at the ends of the lay and another at the center, acting alternately on both shuttles. The use of the central picker is rendered possible by a special stopmotion device at the central shuttle box, which becomes alternately operative, according as the right hand or the left hand shuttle enters the box.

The invention also comprises special means for regulating the winding of the several webs. Both the webs are simultaneously drawn along, but they may be wound at the same speed or at different speeds, the latter being, for instance, the case when the reduction of the two pieces is not the same.

The invention also comprises certain other features and devices connected with the operation and control of the loom, all of which will now be particularly described with reference to the accompanying drawings.

The drawings show by way of example a loom for simultaneously weaving four webs, in two planes one above the other.

In the drawings Figure l is a front elevation of the machine, Fig. 2 a side view, Fig. 8 a vertical section on the line 33 of Fig. 1, and Fig. 4 is a cross-section on the line 4E-t of Fig. 1, Fig. 5 is a front view, on a larger scale, of the mechanism for actuating the picker of the central shuttle box. Fig. 6 a side view thereof, and Fig. 7 a plan view. Fig. 8 is an elevation of the central shuttle box, with its driver, Fig. 9 a plan view thereof, partly in section on the line 9 9 of Fig. 8, and Fig. 10 a rear view. Fig. 11 is a cross-section of the said shuttle box, on the line 1l-11, of Fig. 10. Fig.

12 is a perspective elevation of the driver of the central shuttle box.

In Fig. 1, A A are the posts of the frame, connected to each other by beams B. One of the latter supports four standards A which have bearings for the upper cloth beams K of four pairs of cloth beams K, L, two at each side of the vertical median plane, arranged as shown in Fig. 4:, the lower cloth beams L being supported by pivoted forks L 0, C, are warps drawn ofi beams D, and C C are the webs. E represents the heddles and F the lay, the swords F of which support the shuttle boxes G, G, and g. The cranked shaft M rocks the lay and imparts rotation to the camshaft P which actuates the picker staffs J, J, and j pivoted to holders S, S, s on the rock shaft T to which the swords of the lay are fixed. All these parts are of known type.

I. Regulator of tar/k640 m0tz'0n.-To the shaft T is fixed a V-shaped lever V. Upon the apex of this lever rests a vertically slidable rod IV, to which is fixed a star-shaped piece w carrying four pawls X, each engaged with a ratchet wheel Y. The rocking movement of the shaft T and lever V reciprocates the rod W and causes the ratchet wheels Y to be rotated by the pawls X. The spindles of the ratchet wheels Y are provided with worms y gearing with worm wheels Z, which are keyed to the gudgeons Z of the cloth beams K. The webs travel over the beams K and then on to the beams L, on which they are wound, the beams L with the cloth thereon being thrust firmly against the beams K. All the beams K rotate simultaneously, at a speed which depends in the case of each beam K, on the amplitude of the movementof the rod 7 and on the diameter of the respective ratchet wheel Y. The movement of the rod W being constant, the speed of each beam K depends in practice on the diameter of the ratchet wheel Y, so that the speeds of the beams can be changed independently of each other by changing the wheels Y. In this way the beams are caused to rotate more or less quickly according to the required reduction. The result obtained with this -mechanism is equal to that obtained with four ordinary take-up regulators, though the former comprises fewer parts.

II. Picker-m0ti0n.-The picker staffs J of an arm 2 fixed to one end of a shaft 3, to

the other end of which is fixed a rock-arm 4. The arm 4 is laterally enlarged at its upper end, as best shown in Fig. 7, and carriers two rounded abutments 7 resting upon rollers 6 mounted upon arms of a socket 5 by means of which the staff j is connected to its holder 3. The purpose of the rollers 6 is to reduce the friction due to the forward and rearward rocking movement which is imparted to the staff socket, in addition to lateral rocking movement, to enable the staff to follow the movements of the lay. The cam Q imparts two effective strokes to the picker staff 12 at each stroke of the lay.

III. Central shuttle-bow and stop-motion mechanism.The central shuttle-box g is open at both ends and .comprises two compartments g and located one above the other. The stop-motion mechanism is of the type which acts automatically when either of the shuttles fails to arrive in the box toward which it has been driven. Each of the lateral shuttle-boxes G is provided with a device Gr (Figs. 1 and 2) of known type, for this purpose, and the central shuttle-box is provided with shuttle-operated mechanism which can be adjusted so as to alternatively disable either of the lateral stop-motion devices, the adjustment being automatically ef fected during the working of the loom so that said disabling mechanism always disables the stop motion at the lateral box whence the shuttles have arrived. This mechanism is shown in Figs. 8, 9, 10 and 11.

At the rear of the box 9 a bar 19, bifurcated at its ends, is reciprocatable by means of a lever 29 rocking as indicated by arrows a Z) in Fig. 10. Two pairs of abutment levers 13 and 14 are hinged to the ends of this bar 19, by means of pivots 20, and these levers have bosses 13 and 1 1 protruding through slots 15 and 16 into the upper and lower compartments of the box 9. Said levers also have bosses 17, 17 and 18, 18 at the rear, adapted to coact with two pairs of rollers 27 and 28, the rollers 27 and 28 being mounted, respectively, on the ends of double armed levers 25 and 26 pivoted to curved arms 23 and 24 fixed to stop-motion spindles 21 and 22 respectively. The latter extend to the lateral shuttle-boxes G G.

The bar 19 is reciprocated synchronously with the picker motion, but moves to the left while the picker staff j is moving to the right, and vice versa. When the bar 19 moves in the direction of the arrow 6 (Fig. 10) the rollers 28 are thrust to the rear by the bosses l8. I/Vhen thereupon the shuttles enter the box, and act on the bosses protruding thereinto, they rock the spindle 22 by meansof the rollers 28, and the checking dog of the spindle 22 is lifted, but the spindle 21 is not similarly operated, owing to the fact that the rollers 27 are not on the bosses 17 and the checking dog of this spindle 21 will stop the loom unless said spindle has been operated by the arrival of shuttles in the box G at its opposite end.

If one of the shuttles fails to arrive in the box 9, one of the rollers 18 will not be thrust back, so that the lever 26 will rock on its pivot on the arm 24, and the dog will cause the loom to stop.

When the bar 19 is moved in the direction of arrow (0, the rollers 27 ride on to the bosses 17, and are ready for actuation by the shuttles arriving from the opposite direction.

The lever 29 is pivoted to a beam 30 (Fig. 3) fixed to the swords of the lay, and is rocked by engagement with the arm 4 already described.

The driver 12 in the box 9, best shown in Fig. 12, is approximately H-shaped, comprising two vertical limbs 31 and 32 with curved inner surfaces, fixed into a slotted cross-bar 36. Blocks 33 and 3 1 are fixed to the upper and lower ends of the said limbs, and are respectively located in the upper and lower compartments of the box 9 (Fig. 11). The box 9 has a slot 35 for the pickerstaff j, and the latter engages the slotted bar 12 between the two limbs 31 and 32 of the driver.

Each vertical limb of the shuttle acts in turn on two shuttles, by means of the blocks 33 and 3 1, which act with equal force, driving the shuttles with uniform speed. If there are more than two compartments in the shuttle-box g the limbs 31 and 32 are lengthened and provided with additional blocks for driving shuttles.

It will be clear that without departing from the principle of the invention the loom may be constructed to simultaneously weave six, eight and any other even number of webs.
